Task link help

[Tarkara]

I'm very new to project and have what I hope is not too annoyingly basic of a question!



I need to schedule multiple tasks, and link them in a way that they can occur in any order, but not simultaneously. Is there an easy way to do this? The only option I could think of was to add a resource and assign it to this task 100% but I thought that might go wrong down the road as I added other resources to the task.

The project I'm building it to manage a clinical trials team, so the reason the tasks cannot be simultaneous is that the trial participant obviously needs to be at them all.

Any help would be greatly appreciated!

I'm afraid it's not possible.

By definition, when linking you are setting an order based upon the predecessor's start or finish and the successor's start or finish. Link them how you *think* it will happen and then be prepared to adjust when the trials start.

I imagine some sort of decision about which trials starts when is made before the trials actually start?
